FENCE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 389,129, dated September 4, 1888.

Application filed Aprll 28, i888.

To @ZZ whom it may concern:

Be it known that I, JOHN M. VRIGHT, a citizen of the United States, residing at Mundy, in the county of Genesee and State of Michigan, have invented a new and useful Improvement in Fence-Machines, of which the following is a speciiication.

My invention relates to improvements in fence machines; and it consists in certain novel features hereinafter fully described and claimed.

In the accompanying drawings, which fully illustrate my invention, Figure l is a perspective view of my improved machine,showing its position on a level surface. Fig. 2 is a side view showing it adjusted for work on an inclined surface. Figs. 3 and 4 are detail views showing the wire twisting device.

Referring to the drawings by letter, A designates the usual standard supporting the wiretwisting devices and pivoted at its lower end to the base B. The base B consists of the two parallel branches C C, each of which consists of a metallic loop having the rollers D in its ends, by means of which the device may be moved from place to place. The lower end of the standard is pivoted to the base near one end of thesame,asshown,and at the opposite end of the baseI erect the post E, which is provided in its upper portion with a longitudinal series of transverse openings, F.

G designates a brace, which has its lower end pivoted upon the same pivot which secures the standard A to the base. The upper end of this brace is provided with alongitudinal series of openings, H, any one of which is adapted to register with one of the openings in the post, a bolt, I, being inserted through the registered openings.

J designates a bracket, the lower' end of which is secured to the post by the bolt I, its upper end being bent outward from the post. A nut or perforated block, K, is journaled between the post and the upper end of the bracket by means of trunnions L, engaging suitable openings in the bracket and the post. It will be observed from the foregoing that the bracket, the post, and the brace are connected together by a single bolt, and that the brace and post can be readily adjusted to hold the post rigidly at any desired angle to the base.

Serial No. 272,095. (No model.)

At a suitable point on the standard A, I pro vide the ears or lugs M, between which a nut, N, is pivotcd.

O designates a crank-shaft having its opposite ends provided with oppositelyturned screw-threads and engaging the nuts K N, as shown.

In Fig. l the normal position ofthe parts is shown. When it becomes necessary to operate the device on a hillside or other inclined surface, the crank-shaft is turned in the proper direction to force its ends through the nuts, and the standard is thereby tilted, as shown in Fig. 2. Of course,when so desired, the standard may be tilted in the reverse direction. The standard is composed of two parallel vertical branches, as shown, and at proper points of the height thereof I secure the bearings P, in which are journaled the sprocket-wheels Q, around which passes an endless sprocketchain, R, which also passes around a driving sprocket-wheel, S, which is journaled between two parallel arms, T T, which project laterally from the standard, near the upper end of the same. The shaft of the sprocket-wheel is provided with a crank-handle, U, by lneans of which the device may be operated. The sprocket-wheels Q have hollow spindles,and in these hollow spindles I mount the wire twisters V, which consist of wire guide bars or plates having two or morel transverse openings, IV, through which the wires are passed.

In Fig. -I I have shown the wire twister as composed of a loop or slotted bar, in which I journal the small grooved rollers X. V'Vhen the fence n is composed of two wires twisted around each other, this latter forni of device is used, the wires being passed between the outer portions of the rollers and the ends of the slotted bar. Then the driving-wheel is rotated,its motion will he communicated to the smaller sprocket-wheels, as will be readily understood, and the wires consequent-1y twisted around each other. The form shown in Fig. 3, however, is the preferable form, and is especially adapted for twisting two wires upon a central third wire. The central wire is passed through the central openingin the twisting or wire-guide bar and the side wires are passed through the end openings in the same. IVhen the twisting-bars are rotated, the outer IOO Wires are wrapped around the central wire, as will be readily understood.

Of course it will be understood that pickets are secured in the wires at proper points, and as the fence is built the machine is moved over the ground. l

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. The combination of the base, the standard pivoted thereto and carrying the twisting dcvices,the post erected on the base, n uts mounted ou the standard and the post, and a threaded crank-shaft engaging said nuts and extending between the post and the standard, for tilting the standard, as set forth.

2. The combination of the base, the standard pivoted to the base and carrying the twisting devices, the post erected on the base, the brace pivoted to the base and adj ustably secured to the post, and a crank-shaft extending between the standard and the post and geared to the same, for tilting the standard, as set forth.

3. The combination of the base, thestandard pivoted thereon and carrying the twisting devices, the postl erected on the base, the brace secured to the post and the base, the bracket, a single bolt passed transversely through the brace, the post, and bracket, and the crankshaft having bearings in the said bracket and the standard, as set forth.

4. The combination of the base, the standard carrying twisting mechanism and pivoted thereto, the post erected on the base, the bracket secured to the post, the nuts mounted on the standard and between the bracket and the post, and the threaded crank-shaft working in said nuts, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in pres- 4o ence of two witnesses.
